September 2010 the Vote for my blog competition was launched. On the H&M Facebook page (6 million fans) and Twitter feeds (2 million followers) we simply dropped messages like "H&M loves fashion and style blogs. Take part in our global "Vote for my Blog" competition" and "The blog that receives the most votes will win exclusive first showing of the Lanvin for H&M Fashion Show Trailer. Yes it's true. One Blog!" was posted. Very direct, aiming for the ego. Also an e-mail was sent out to several influential bloggers. Now the bloggers knew about an alluring exclusive trailer. Bloggers rapidly joined the competition.After the 3 campaign weeks, during which people had been able to follow the progress through Facebook and all widgets, the winner was announced by switching all widgets from voting to promoting the Lanvin Show for H&M, and finally the actual collection on H&M.com. 3 in 1.

The first primary goal was to generate awareness and hype around the Lanvin for H&M collaboration through "free" spread via social media.
